ELEoTmoAL'oUT-OUT.

SPECIFICATION forming part of Letters Patent No. 789,295, dated May 9,1905. Application led May 8, 1903. Serial No. 156,287.

T0 all whom, it Netty concern.- Be it known that I, WILLIAM D. PACKARD,a citizen of the United States of America, and a resident of Warren, inthe county of Trumbull and State of Ohio, have invented certain new anduseful Improvements in Electrical Out-Outs, of which the following is aspecification.

The present invention is particularly applicable for use withtransformers for hightension currents, although certain of its featuresInay be used in other classes of switches and cut-outs.

The invention will be described in detail in connection with theaccompanying dravings, in which- Figure 1 is a vertical section on theline A of Fig. 2. Fig. 2 is a similar section on the line B of Fig. 1.Fig. 3 is a perspective view of the switch-lever removed from itscasing, and Fig. 4 is a section on the line C of Fig. 2. Figs. 5 and 6are views similar to Figs. 1 and 2, showing a different form ofswitch-lever.

The particular form of switch or cut-out illustrated in the drawings isdesigned for outdoor use, provision being made for keeping out rain andfor connecting it to poles or buildings.

The parts are connected to a casing or body 1, which is preferablyconstructed of porcelain or other durable non-conducting material. Thebody is generally bell shape, being closed at the top and provided witha skirt 2, extending below the electrical connections to prevent accessof water to them. It is provided with suitable openings 3 forsupporting-screws. A circular cap 4 is connected to the body, the rim orskirt of the cap extending beyond the body to shed water. The upper endof the body is partially tapered or conical, and the cap has a conicalrecess on the under side in which the body iits. A plug or stem 5 ofconducting material extends through a central vertical opening in thetop of the body, the upper end of the stem being threaded, while thelower end is in the form of a flat blade 6, extending into the centralopening 7. The stem 5 is connected to the body by a nut S, and a secondnut 9 is provided for clamping the incoming conductor 10 to the stem.The conical top of the body is provided with one or more grooves 11 toreceive the conductor. The cap 4, which is also formed of porcelain orother durable non-conducting material, is provided with a threadedopening adapted to engage with the spindle 5. As shown, a nut 12 isembedded or cemented in the cap for this purpose.

A switch-lever 13, which is formed of porcelain, iiber, or othersuitable non-conducting material, is provided with clips 14 at itsAupper end which receive between them the blade 6, and at its lower endit is provided with a blade 15, which coperates with clips 16 on'thebody. The clips 14 are of spring material and are provided with, abindingpost 17, fromV which a conducting-wire 1S extends to a secondbinding-post 19, connected with the blade 15. The parts 6 and 14 form aknife-switch7 and have a sufficient 'frictional engagement to sustainthe lever in its working position in the cut-out and also to hold it inany position it may be placedthat is, either with the circuit openorclosed. The knife-switch 15 16 is arranged at right angles to the.switch 5 14, and the latter forms the pivotal point about which thelever works to open and close the former. ln both cases we have arubbing contact which keeps the parts in good working order. The levercan be removed by simply opening the switch 15 16 and then pulling itout of the casing, thus providing for inspection or repairs and alsoproviding for permanently breaking the circuit when it is desired to doso. The switchlever is provided with a suitable handle 20, extendingbelow the skirt ofthe casing. The terminal 21 of the line-circuit isconnected to a binding-post 22, attached to the clips 16.

Referring to Figs. 5 and 6, the lever therein shown has a socket 23 'forreceiving an inclosed plug-fuse 24, which serves as a conductor and afuse in the usual manner. This plug-fuse has a metal cap 25 at its upperend which is engaged by spring-fingers 26, connected to a head on thestem 5. The frictional contact between the head 25 and said fingers issnilicicnt to hold the switch-lever in place. Said parts also form apivot about IOO which the switch-lever turns. A metal cap 27 on thelower end of the plug-fuse is engaged between spring-lingers 28, similarto the spring-fingers 26. These latter springiingers are rigidlyanchored in the switchlever 13, and they are connected electrically withthe plate 15, which coperates with the clips 16.

The operation of the switch shown in Figs. 5 and 6 is practically thesame as of the switch previously described. It will be noted, however,that it also includes the plug-fuse and that said fuse may be uicklyremoved and replaced, being held on y by frictional contact with theclips or spring-lingers 26 28.

It will be noted that in bothforms of switch shown a switch-lever isheldin place frictionally and may be readily withdrawn fromits housingand that it turns about the point-.of frictional engagement with thefixedclipsin the housing.

Having described.l my invention, what I claim, and desire to secure byLetters Patent, is`

1. An electrical cut-out comprising a hollow body open only at its lowerend, and a switch-lever adapted to be insertedand-withdrawn at the lowerend of the body, a switch for connecting the upper end of the lever tothe body electrically andmechanically, and a second switch adapted to beopened and closed by the swinging of; the` levery about said lirst-namedswitch.

2. An electrical cut-outl comprisinga hollow body of non-conductingmaterial open only at its lower end, an electrical connection betweenthe interiorand exterior at the4 upper end, a switch-lever withinthebody and in contact with said connection, anda cap of non-conductingmaterial removably secured to the upperendof the body andadaptedtoprotect the electrial connections.

3. An electrical cut-out comprising a hollow non-conducting body open atits lower end and having a conical upper end with one or more exteriorgrooves therein to receive an electrical terminal, a cap having aconical recess in its lower side adapted to lit closely over the body,and means for connecting the cap to the body.

4. An electrical cut out comprising a switch-lever and two iiXedterminals, said switch-lever having a knife-switch at one end connectingwith one terminal and a knifeswitch at the otherfendatfright angles tothe first-named knife-switch and adapted to connect with the otherterminal whereby said switch-lever is provided with rubbing contacts andis readily removable.

5. An electrical cut-out comprising abody, a lever within the body, adetachable plugfuse located within the lever, contact plates or fingersconnected with the lever and engaging said plug-fuse to hold the samewithin .the lever, an ,contactplates or lingcrsconnected with the bodyand arrangedl toengage the. opposite end of said plug-luse and toholdthe lever removable within .the body.

6. Anelectrical cut-out comprising ahollow body of non-conductingmaterial :open at its lower end, an electrical connection passingthroughthe uppervendiof saidibody, contact plates or ingers inthe upperendof the body, a levenwithinzthe body having similar contactiplatesoriingcrs, a removable plugfuse connecting the contact platesorlingers on the lever-with the, contact plates or fingers onthe body,andia knife-switch adapted to connect the lever at the terminal Aatthelower end of the body.

7. An electricalcut-out comprisingahol.- low body of non-.conductingmaterial open at its lowery end, two contacts within saidbody adapted tohave the terminals.ofganelcctric. circuit. connectedi therewith, and; a.switchlever adapted to electrically connectsaid contacts anditosuccessively breakthe. circuit at said ,contacts as itis movedirstlaterally and then longitudinally.

In. testimony whereof ly have signed my name to this specilication inthe presence, ol twofsubscribing witnesses.
